I'd go along with what Radkoch pointed out. Even though the build will still be basically a "parts gun", having all Imbel parts (minus the min US ones) will be a plus in some circles.
A few years from now, the DSA receivers and other US made ones will still be around, but Imbels will be rare and sought after by those wanting an all Imbel gun. Just something to keep in mind.
I got two more Imbel receivers from Classic when they got them in a month or so back. They both looked as good as the others I've purchased over the years. Wish I had gone for four now.
